Axial-flow hydrocyclone is a new type of hydrocyclone which is proposed on the basis of tangential hydrocyclone. Its key part is rotating and accelerating component – the guided vane. The structural particularity made it necessary to pay attention to the internal flow field of axial-flow hydrocyclone. In view of the progress of CFD technique and mature of calculation condition, numerical simulations...
CNC machining is an important process to solve problem of difficultly machining for single-crystal sapphire. In order to receive single-crystal conformal sapphire dome, this paper reviews a series of processing experiments, analysis and optimization of process parameters. It receives a set of complete conformal sapphire dome CNC machining technology and the optimal process parameters.
Since 1980, UPMIS has developed rapidly in China. There are some problems in UPMIS: management mechanism, information standard, information sharing, system integration, data update, 3D modeling, and UPMIS of China should enhance electronic submit technology, virtual reality technology, interactive information sharing platform, information real-time renewal technology, information technology legalization.
